Location
Cause → Event → Consequence
In 215 CE, Sun Quan attempted to seize the strategically important Hefei fortress but was repulsed by Cao Cao's garrison under Zhang Liao and forced to withdraw after a plague struck his forces. This defeat prompted Cao Cao to begin preparations for a retaliatory campaign against Sun Quan's territory.
In 217 CE, Cao Cao personally commanded his navy southward to Ruxukou to confront Sun Quan in a decisive engagement. The battle represented a direct clash between the two major warlords in the Huai River region during the twilight of the Eastern Han dynasty.
The battle at Ruxu in 217 followed an earlier 213 CE engagement at the same location and formed part of the ongoing strategic contest between Cao Cao and Sun Quan for dominance over the Yangtze River basin. The source does not record a definitive victor or detailed outcome for this engagement.
